Belitsoft > Reliable SaaS Development Company

Reliable SaaS Development Company

Software development company Belitsoft possesses significant experience in creating successful custom SaaS applications for various industries. Businesses from the USA, the UK, Israel, and Europe, including startups and enterprises, have benefited from our services by cutting costs through outsourcing the development of their SaaS products in Europe. Explore our recent SaaS case studies.

SaaS Web Development

We pay special attention to best practices to design reliable, secure, and cost-effective SaaS systems tailored to your needs.

SaaS Application Architecture. Our expertise is in building multi-tenant SaaS systems, where each of your customers shares common resources, from compute services to storage and messaging. Depending on your SaaS business needs, compliance requirements, and the nature of your solution, we can deploy a mixed-tenant architecture. This approach allows some premium tenants to have their own distinct database or even a completely independent infrastructure stack, such as individual Virtual Private Clouds. Meanwhile, other customers or certain microservices can continue in a multi-tenant setup.

SaaS Onboarding and Tenant Identity. Our approach goes beyond just implementing an identity provider for authentication; we ensure you always understand the tenant association of each user. You'll possess the capability to update, manage, and operate all customers collectively through shared services like user registration, management, and provisioning; tenant management and administration; system administration; billing management, and metrics management. A frictionless, repeatable onboarding self-service or internally executed process to both B2C and B2B customers enables you to support rapid growth in your customer base without incurring substantial operational overhead.

SaaS Customization. Anticipating that some of your customers may seek customizations, we can integrate these as configuration options available to all your clientele. By embedding these features at the heart of your offering, your SaaS company can support unique customer requirements without compromising operational efficiency or your business's innovation objectives. Belitsoft has expertise in application modernization. We add the most requested features from your customers to your existing SaaS platform. For examples of our work, check out our cases on healthcare SaaS customization, insurance SaaS customization and cybersecurity SaaS customization.

SaaS Usage Metrics. We identify workflows and events such as consumption data, and latency metrics, and then publish them to a data warehouse for aggregation. Based on that data, SaaS operations dashboards will provide you with both global and granular views of the health and activity of your tenants. Your team can drill into the operational data for individual tenants like the features tenants use, the load they place on your system, potential bottlenecks, cost profiles, and more to identify opportunities to evolve the SaaS system. Detailed dashboards and visualizations will display CPU and memory usage, total data transfer and network costs, and total data and storage costs. Based on that data, we can build alarms and automation to heal the system without experiencing an outage.

SaaS Performance. We design SaaS systems to ensure basic tenants don't impact the performance of premium ones. It can be based on the principle that a tenant's resource allocation should correlate with the revenue they generate. To manage this, we use throttling policies for individual tenants. When a tenant reaches their limit, throttling is applied. We can use the API Gateway to implement this throttling based on usage plans with set SLAs. We take measures to prevent disruptions from noisy tenants and ensure resources are safeguarded from cross-tenant access, whether using a serverless application microservices or Kubernetes container-based model.

SaaS Billing Architecture. You will get a clear picture of how your tenants are influencing costs, enabling you to make strategic decisions about how to build, sell, and operate your SaaS application. We design and develop a consumption mapping model to illustrate how tenants utilize the resources of your SaaS system. This model facilitates the allocation of specific consumption percentages to each tenant. The group of clients generating the least revenue will receive a smaller resource portion, while those generating the highest revenue will be allocated a more substantial pool. To align costs with actual activity and ensure effective resource consumption scaling, we measure and attribute costs in a multi-tenant environment. Our focus is on gathering data from areas that significantly impact your cloud infrastructure bill. As a result, you can gain insights into the per-tenant costs. We can integrate consumption-based pricing or pay-as-you-go models with other pricing strategies, such as subscription models. By integrating metering data with a billing system and establishing limits, we ensure the SaaS application's infrastructure consumption remains consistent with real-time tenant activity trends. This visibility into tenant cost profiles enables you to offer differentiated pricing and experiences suited to diverse customer profiles.

SaaS Testing

With our software testing services, we are not just ensuring that the functionality of your application works as expected. We also focus on testing SaaS system reliability challenges, like how it responds to the unexpected and how effectively it scales. Automation testing allows us to handle unpredictable load in a multi-tenant context, identifying key load and performance issues before they affect your customers. Our testing areas include:

Cross-tenant Impact Tests

We simulate scenarios where one tenant group places a disproportionate load and determine how the system responds. If the system consists of separate services, we test the scaling processes for each.

Tenant Consumption Tests

We track resource and tenant activity metrics, determine the difference, and apply it to a monitoring policy to identify suboptimal resource consumption.

Tenant Onboarding Tests

A spike should not disrupt the onboarding process, especially with dependencies on third-party integrations like billing. We test to ensure fallback strategies handle potential outages for these integrations effectively.

API Throttling Tests

“Free” subscribers should not impose the same load as “gold” subscribers. We test that throttling policies are applied successfully.

Tenant Isolation Testing

We ensure that each client's data and infrastructure are secured and not accessible by other clients.

Tenant Workflow Tests

We select key workflows of your solution and focus load on them to identify if they cause bottlenecks or over-allocation of resources.

Frequently Asked Questions

To choose a SaaS application development partner, consider their experience in the field. Evaluate their portfolio and case studies to see if they've worked on projects similar to yours. Also, read client testimonials and reviews on platforms such as Clutch and Goodfirms for insights into their reputation and work ethics. This information can guide you in making an informed decision when picking a partner.
Building and launching a product can take between 2 to 10 months, depending on factors like the application's complexity and scale, the technology stack, and the number of developers involved in the process.
The cost of developing a SaaS application can vary depending on the location of your team. Hiring from the US may cost around $120,000 per app, while outsourcing the development process to Eastern Europe could significantly reduce the cost to around $50,000.
Multi-tenant app architecture, in either single or multi-instance form, provides cost-effective and scalable solutions. It's easier to manage and accommodate new tenants compared to single-tenant architecture. This model allows the flexibility to start small and expand as needed, ensuring a seamless software experience for your clients.
Developing a scalable SaaS platform or app calls for careful attention to the architecture and infrastructure during planning. This includes optimizing the application's database and caching methods, and selecting a cloud-based platform capable of handling increasing traffic. Furthermore, adopting a microservices architecture is vital, as it enables developers to create and deploy individual application components, simplifying the expansion and modification of the program.
Safeguarding user data is a top priority when developing any SaaS application. Developers should employ a multi-layered security approach that incorporates encryption, access limitations, and frequent vulnerability assessments. It's also of utmost importance to comply with data privacy regulations such as the General Data Protection Regulation (GDPR) and to adhere to industry-standard security measures like the Payment Card Industry Data Security Standard (PCI-DSS).
When it comes to integrating third-party services into a SaaS application, careful planning is paramount. Selecting reliable services that align with your business needs is a must. Developers should ensure the integration is secure and doesn't compromise user data, and comprehensive testing of the integration is needed to confirm smooth operation before launch.
For effective testing and deployment of a SaaS application in a CI/CD environment, automation and collaboration between development and operations teams are necessary. Employing testing frameworks and techniques that support continuous testing and integration of new features is a significant aspect. Moreover, developers can take advantage of orchestration and containerization solutions to create applications that can be deployed swiftly and efficiently.
